I must concede this does not help make these parts readable in the source.
The point that Martin raised is the worst for me: if the processing of this 
workaround is depend on the version of Asciidoc[tor], the way of writing this 
formatting for stuck parts in a compatible way must be clearly defined (and 
made understandable).

I came up with this trickery because of the use of "legacy" Asciidoc format, 
which does not understand unconstrained formatting (doubling the signs, so 
that they don't care about word boundary). With the new format, we would 
simply write:

__<directory>__``/.git``
``--filter=``__<filter-spec>__

Without having to pay attention to the surrounding characters.

For now, we are stuck with the compatibility with the existing tools. I will 
try an propose something else. Would preprocessing be accepted?
